Abstract
The present invention discloses a backlight control method having dynamic backlight adjusting mechanism used in a display control circuit is provided and includes the steps outlined below. A frame refresh time length of a former frame is obtained. When a current frame is started to be displayed, a backlight module is controlled to output a strobe backlight in a backlight turn-on time period. When an actual display time reaches the frame refresh time length and a next frame is not started to be displayed, the backlight module is controlled to output a constant backlight until the next frame is started to be displayed. When the actual display time does not reach the frame refresh time length and the next frame is started to be displayed, the backlight module is controlled to output the constant backlight until the frame next to the next frame is started to be displayed.
